Simplifying 2x2 + 12x = 5x + 3 Reorder the terms: 12x + 2x2 = 5x + 3 Reorder the terms: 12x + 2x2 = 3 + 5x Solving 12x + 2x2 = 3 + 5x Solving for variable 'x'. Reorder the terms: -3 + 12x + -5x + 2x2 = 3 + 5x + -3 + -5x Combine like terms: 12x + -5x = 7x -3 + 7x + 2x2 = 3 + 5x + -3 + -5x Reorder the terms: -3 + 7x + 2x2 = 3 + -3 + 5x + -5x Combine like terms: 3 + -3 = 0 -3 + 7x + 2x2 = 0 + 5x + -5x -3 + 7x + 2x2 = 5x + -5x Combine like terms: 5x + -5x = 0 -3 + 7x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1.5 + 3.5x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + 3.5x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + 3.5x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + 3.5x + x2 = 0 + 1.5 3.5x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 3.5x + x2 = 1.5 The x term is 3.5x. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5x + 3.0625 + x2 = 1.5 + 3.0625 Reorder the terms: 3.0625 + 3.5x + x2 = 1.5 + 3.0625 Combine like terms: 1.5 + 3.0625 = 4.5625 3.0625 + 3.5x + x2 = 4.5625 Factor a perfect square on the left side: (x + 1.75)(x + 1.75) = 4.5625 Calculate the square root of the right side: 2.136000936 Break this problem into two subproblems by setting (x + 1.75) equal to 2.136000936 and -2.136000936.Subproblem 1
x + 1.75 = 2.136000936 Simplifying x + 1.75 = 2.136000936 Reorder the terms: 1.75 + x = 2.136000936 Solving 1.75 + x = 2.136000936 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = 2.136000936 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = 2.136000936 + -1.75 x = 2.136000936 + -1.75 Combine like terms: 2.136000936 + -1.75 = 0.386000936 x = 0.386000936 Simplifying x = 0.386000936Subproblem 2
x + 1.75 = -2.136000936 Simplifying x + 1.75 = -2.136000936 Reorder the terms: 1.75 + x = -2.136000936 Solving 1.75 + x = -2.136000936 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = -2.136000936 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = -2.136000936 + -1.75 x = -2.136000936 + -1.75 Combine like terms: -2.136000936 + -1.75 = -3.886000936 x = -3.886000936 Simplifying x = -3.886000936Solution
